over whelmed!!

I am a mother of four. I work a full time job and I recently started taking 8 hours of classes. I feel like I dont have any extra time at all. My husband and I get to bond at night two or three nights a week and the other nights I am usually doing home work or studing for a test. Maybe I took on to much! I really want to earn a degree but li. Is difficult with so much on my plate. My kids are 5, 6, 7 years old & an 8 month old. I wish I didnt have to work and I vould just focus in school. I have hinted around a few times to my husband about it but he doesnt pick up on them. Lol
